The EPS focus its work on individuals, aiming to identify special needs and to give advice to teachers and parents when they ask for it. In addition, the service also give priority to prevention and system intervention in kindergartens and schools. To master these big tasks university courses are established to support EPS counsellors' continuous learning. There is, however, a need for more in-depth and systematic knowledge on how they experience the courses they attend. In this study, EPS counsellors’ reflection logs during a particular course are investigated. The research question is: what are the content and priorities of the reflections that are communicated in the logs produced by the educational psychological counsellors during a post-graduate course? The investigated course is a credit course organized over a one-year period in two one-semester modules. The altogether 55 students enrolled in the course work as EPS counsellors in various municipalities across Norway. At the end of each day throughout the course period, the participants wrote reflection logs about what they had experienced during the day. The data material consists of 165 pages of typed text. The collaborating researchers studied the data material to ascertain, differentiate and understand the meaning of the content in each log. The analysis also involved the search for similarity in content and development of analytical categories that described the focus and primary concerns in each of the written logs. This involved constant 'critical and sustained discussions' for mutual construction of meaning between the co-researchers in the developing categories. The process is inspired by Grounded Theory. This means that the concepts developed during the analysis derived from the data material and not chosen prior to the investigation. The analysis revealed that the concept 'Useful' frequently appeared in the participants’ reflections and, as such, 'Useful' serves as a core category. The core category is described through three major categories: (1) knowledge sharing (concerning direct and indirect work with students with special needs) with colleagues is useful, (2) reflections on models and theoretical concepts (concerning students with special needs) are useful, (3) reflection on the role as EPS counsellor is useful. In all the categories, the notion of useful occurs in the participants’ emphasis on and acknowledgement of the immediate and direct link between the university course content and their daily work practice. Even if each category has an importance and value of its own, it is crucial that they are understood in connection with one another and as interwoven. It is the connectedness that gives the core category an overarching explanatory power. The knowledge from this study may be a relevant contribution when it comes to designing new courses that support continuing professional development for EPS counsellors, whether for post-graduate university courses or local courses at the EPS offices or whether in Norway or other countries in the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructing%20and%20circulating%20knowledge" title="constructing and circulating knowledge">constructing and circulating knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=educational-psychological%20counsellor" title=" educational-psychological counsellor"> educational-psychological counsellor</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20development" title=" professional development"> professional development</a> </p> <a href="https://publications.waset.org/abstracts/95102/constructing-and-circulating-knowledge-in-continuous-education-a-study-of-norwegian-educational-psychological-counsellors-reflection-logs-in-post-graduate-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95102.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7979</span> High-Throughput, Purification-Free, Multiplexed Profiling of Circulating miRNA for Discovery, Validation, and Diagnostics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Hidalgo%20de%20Quintana">J.

The assay combines particlebased multiplexing, using patented Firefly hydrogel particles, with single step RT-PCR signal. Thus, the Circulating microRNA assay leverages PCR sensitivity while eliminating the need for separate reverse transcription reactions and mitigating amplification biases introduced by target-specific qPCR. Furthermore, the ability to multiplex targets in each well eliminates the need to split valuable samples into multiple reactions. Results from the Circulating microRNA assay are interpreted using Firefly Analysis Workbench, which allows visualization, normalization, and export of experimental data. To aid discovery and validation of biomarkers, we have generated fixed panels for Oncology, Cardiology, Neurology, Immunology, and Liver Toxicology. Here we present the data from several studies investigating circulating and tumor microRNA, showcasing the ability of the technology to sensitively and specifically detect microRNA biomarker signatures from fluid specimens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title="biomarkers">biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=biofluids" title=" biofluids"> biofluids</a>, <a href="https://publications.waset.org/abstracts/search?q=miRNA" title=" miRNA"> miRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=photolithography" title=" photolithography"> photolithography</a>, <a href="https://publications.waset.org/abstracts/search?q=flowcytometry" title=" flowcytometry"> flowcytometry</a> </p> <a href="https://publications.waset.org/abstracts/46466/high-throughput-purification-free-multiplexed-profiling-of-circulating-mirna-for-discovery-validation-and-diagnostics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46466.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7978</span> Effect of the Cross-Sectional Geometry on Heat Transfer and Particle Motion of Circulating Fluidized Bed Riser for CO2 Capture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seungyeong%20Choi">Seungyeong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Namkyu%20Lee"> Namkyu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Il%20Shim"> Dong Il Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Mun%20Lee"> Young Mun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Ki%20Park"> Yong-Ki Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Hee%20Cho"> Hyung Hee Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of the cross-sectional geometry on heat transfer and particle motion of circulating fluidized bed riser for CO<sub>2</sub> capture was investigated.

In this context our aim has been focused on development of a non-invasive. Circulating tumor cells (CTCs) represent a unique liquid biopsy carrying comprehensive biological information of the primary tumor. Herein, we sought to develop a novel score based on the combination of the most significant CTCs biomarkers with and routine laboratory tests for accurate detection of metastatic breast cancer. Methods: Cytokeratin 18 (CK18), Cytokeratin 19 (CK19), and CA15.3 were assayed in metastatic breast cancer (MBC) patients (75), non-MBC patients (50) and healthy control (20). Results: Areas under receiving operating curve (AUCs) were calculated and used for construction on novel score. A novel score named MBC-CTCs = CA15.3 (U/L) × 0.08 + CK 18 % × 2.9 + CK19 × 3.1– 510. That function correctly classified 87% of metastatic breast cancer at cut-off value = 0.55. (i.e great than 0.55 indicates patients with metastatic breast cancer and less than 0.55 indicates patients with non-metastatic breast cancer). Conclusion: MBC-CTCs is a novel, non-invasive and simple can applied to discriminate patients with metastatic breast cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metastatic%20breast%20cancer" title="metastatic breast cancer">metastatic breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20tumor%20cells" title=" circulating tumor cells"> circulating tumor cells</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokeratin" title=" cytokeratin"> cytokeratin</a>, <a href="https://publications.waset.org/abstracts/search?q=EpiCam" title=" EpiCam"> EpiCam</a> </p> <a href="https://publications.waset.org/abstracts/146716/discriminant-function-based-on-circulating-tumor-cells-for-accurate-diagnosis-of-metastatic-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7976</span> An Improved Circulating Tumor Cells Analysis Method for Identifying Tumorous Blood Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salvador%20Garcia%20Bernal">Salvador Garcia Bernal</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Zheng"> Chi Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Keqi%20Zhang"> Keqi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Mao"> Lei Mao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Circulating Tumor Cells (CTC) is used to detect tumoral cell metastases using blood samples of patients with cancer (lung, breast, etc.).

The cells that leave the primary tumor and enter the circulation and cause metastasis in the secondary organs are called "circulating tumor cells" (CTCs). The presence and number of circulating tumor cells has been associated with poor prognosis in many major types of cancer, including breast, prostate, and colorectal cancer. It is thought that knowledge of circulating tumor cells, which are seen as the main cause of cancer-related deaths due to metastasis, plays a key role in the diagnosis and treatment of cancer. The fact that tissue biopsies used in cancer diagnosis and follow-up are an invasive method and are insufficient in understanding the risk of metastasis and the progression of the disease have led to new searches. Liquid biopsy tests performed with a small amount of blood sample taken from the patient for the detection of CTCs are easy and reliable, as well as allowing more than one sample to be taken over time to follow the prognosis. However, since these cells are found in very small amounts in the blood, it is very difficult to capture them and specially designed analytical techniques and devices are required. Methods based on the biological and physical properties of the cells are used to capture these cells in the blood. Early diagnosis is very important in following the prognosis of tumors of epithelial origin such as breast, lung, colon and prostate. Molecules such as EpCAM, vimentin, and cytokeratins are expressed on the surface of cells that pass into the circulation from very few primary tumors and reach secondary organs from the circulation, and are used in the diagnosis of cancer in the early stage. For example, increased EpCAM expression in breast and prostate cancer has been associated with prognosis. These molecules can be determined in some blood or body fluids to be taken from patients. However, more sensitive methods are required to be able to determine when they are at a low level according to the course of the disease. The aim is to detect these molecules found in very few cancer cells with the help of sensitive, fast-sensing biosensors, first in breast cancer cells reproduced in vitro and then in blood samples taken from breast cancer patients. In this way, cancer cells can be diagnosed early and easily and effectively treated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20biosensors" title="electrochemical biosensors">electrochemical biosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20tumor%20cells" title=" circulating tumor cells"> circulating tumor cells</a>, <a href="https://publications.waset.org/abstracts/search?q=EpCAM" title=" EpCAM"> EpCAM</a>, <a href="https://publications.waset.org/abstracts/search?q=Vimentin" title=" Vimentin"> Vimentin</a>, <a href="https://publications.waset.org/abstracts/search?q=Cytokeratins" title=" Cytokeratins"> Cytokeratins</a> </p> <a href="https://publications.waset.org/abstracts/140961/determination-of-circulating-tumor-cells-in-breast-cancer-patients-by-electrochemical-biosensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7974</span> Cold Model Experimental Research on Particle Velocity Distribution in Gas-Solid Circulating Fluidized Bed for Methanol-To-Olefins Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongzheng%20Li">Yongzheng Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiwen%20Sun"> Qiwen Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radial profiles of particle velocities were investigated in a 6.1 m tall methanol-to-olefins cold model experimental device using a TSI laser Doppler velocimeter.

The average particle velocity was close to upward velocity and higher than downward velocity in radial locations except the wall region of riser. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circulating%20fluidized%20bed" title="circulating fluidized bed">circulating fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20doppler%20velocimeter" title=" laser doppler velocimeter"> laser doppler velocimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20velocity" title=" particle velocity"> particle velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20profile" title=" radial profile"> radial profile</a> </p> <a href="https://publications.waset.org/abstracts/25000/cold-model-experimental-research-on-particle-velocity-distribution-in-gas-solid-circulating-fluidized-bed-for-methanol-to-olefins-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25000.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7973</span> Correlation to Predict the Effect of Particle Type on Axial Voidage Profile in Circulating Fluidized Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Khurram">M.

Effects of variables (gas velocity, particle properties, and static bed height) were analyzed on bed voidage. The axial voidage profile showed a typical trend along the riser: a dense bed at the lower part followed by a transition in the splash zone and a lean phase in the freeboard. Bed expansion and dense bed voidage increased with an increase of gas velocity as usual. From experimental results, a generalized model relationship based on inverse fluidization number for dense bed voidage from bubbling to fast fluidization regimes was presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20voidage" title="axial voidage">axial voidage</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20fluidized%20bed" title=" circulating fluidized bed"> circulating fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=splash%20zone" title=" splash zone"> splash zone</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20bed" title=" static bed"> static bed</a> </p> <a href="https://publications.waset.org/abstracts/55004/correlation-to-predict-the-effect-of-particle-type-on-axial-voidage-profile-in-circulating-fluidized-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7972</span> The Role of Instruction in Knowledge Construction in Online Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soo%20Hyung%20Kim">Soo Hyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two different learning approaches were suggested: focusing on factual knowledge or focusing on the embedded meaning in the statements. Each way of learning has positive effects on different question categories, where factual knowledge helps more with simple fact questions, and searching for meaning in given information helps learn causal relationship and the embedded meaning. To test this belief, two groups of learners (12 male and 39 female adults aged 18-37) watched a ten-minute long Youtube video about various factual events of American history, their meaning, and the causal relations of the events. The fact group was asked to focus on factual knowledge in the video, and the meaning group was asked to focus on the embedded meaning in the video. After watching the video, both groups took multiple-choice questions, which consisted of 10 questions asking the factual knowledge addressed in the video and 10 questions asking embedded meaning in the video, such as the causal relationship between historical events and the significance of the event. From ANCOVA analysis, it was found that the factual knowledge showed higher performance on the factual questions than the meaning group, although there was no group difference on the questions about the meaning between the two groups. The finding suggests that teacher instruction plays an important role in learners constructing a different type of knowledge in online learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factual%20knowledge" title="factual knowledge">factual knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=instruction" title=" instruction"> instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=meaning-based%20knowledge" title=" meaning-based knowledge"> meaning-based knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a> </p> <a href="https://publications.waset.org/abstracts/138350/the-role-of-instruction-in-knowledge-construction-in-online-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138350.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7971</span> Zero Voltage Switched Full Bridge Converters for the Battery Charger of Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Ullah">Rizwan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdar%20Ali"> Abdar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced when switching frequency is increased. The increase in the switching frequency increases switching losses. ZVS is used to reduce switching losses and to operate the converter in the battery charger at high frequency. The performance of each of the three converters is evaluated on the basis of ZVS range, dead times of the switches, conduction losses of switches, circulating current stress, circulating energy, duty cycle loss, and efficiency. The limitations and merits of each PWM FB converter are reviewed. The converter with broader ZVS range, high efficiency and low switch stresses is selected for battery charger applications in EV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM%20FB%20converter" title=" PWM FB converter"> PWM FB converter</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20voltage%20switching" title=" zero voltage switching"> zero voltage switching</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20energy" title=" circulating energy"> circulating energy</a> </p> <a href="https://publications.waset.org/abstracts/54708/zero-voltage-switched-full-bridge-converters-for-the-battery-charger-of-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54708.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7970</span> Effects of Different Types of Perioperative Analgesia on Minimal Residual Disease Development After Colon Cancer Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lubomir%20Vecera">Lubomir Vecera</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Gabrhelik"> Tomas Gabrhelik</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Tolmaci"> Benjamin Tolmaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Josef%20Srovnal"> Josef Srovnal</a>, <a href="https://publications.waset.org/abstracts/search?q=Emil%20Berta"> Emil Berta</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Prasil"> Petr Prasil</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Stourac"> Petr Stourac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancer is the second leading cause of death worldwide and colon cancer is the second most common type of cancer. Currently, there are only a few studies evaluating the effect of postoperative analgesia on the prognosis of patients undergoing radical colon cancer surgery. Postoperative analgesia in patients undergoing colon cancer surgery is usually managed in two ways, either with strong opioids (morphine, piritramide) or epidural analgesia. In our prospective study, we evaluated the effect of postoperative analgesia on the presence of circulating tumor cells or minimal residual disease after colon cancer surgery. A total of 60 patients who underwent radical colon cancer surgery were enrolled in this prospective, randomized, two-center study. Patients were randomized into three groups, namely piritramide, morphine and postoperative epidural analgesia. We evaluated the presence of carcinoembryonic antigen (CEA) and cytokeratin 20 (CK-20) mRNA positive circulating tumor cells in peripheral blood before surgery, immediately after surgery, on postoperative day two and one month after surgery. The presence of circulating tumor cells was assessed by quantitative real-time reverse transcriptase-polymerase chain reaction (qRT-PCR). In the priritramide postoperative analgesia group, the presence of CEA mRNA positive cells was significantly lower on a postoperative day two compared to the other groups (p=0.04). The value of CK-20 mRNA positive cells was the same in all groups on all days. In all groups, both types of circulating tumor cells returned to normal levels one month after surgery. Demographic and baseline clinical characteristics were similar in all groups. Compared with morphine and epidural analgesia, piritramide significantly reduces the amount of CEA mRNA positive circulating tumor cells after radical colon cancer surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20progression" title="cancer progression">cancer progression</a>, <a href="https://publications.waset.org/abstracts/search?q=colon%20cancer" title=" colon cancer"> colon cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal%20residual%20disease" title=" minimal residual disease"> minimal residual disease</a>, <a href="https://publications.waset.org/abstracts/search?q=perioperative%20analgesia." title=" perioperative analgesia."> perioperative analgesia.</a> </p> <a href="https://publications.waset.org/abstracts/144502/effects-of-different-types-of-perioperative-analgesia-on-minimal-residual-disease-development-after-colon-cancer-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7969</span> An Improved Modular Multilevel Converter Voltage Balancing Approach for Grid Connected PV System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safia%20Bashir">Safia Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfiqar%20Memon"> Zulfiqar Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decade, renewable energy sources in particular solar photovoltaic (PV) has gained increased attention. Therefore, various PV converters topologies have emerged. Among this topology, the modular multilevel converter (MMC) is considered as one of the most promising topologies for the grid-connected PV system due to its modularity and transformerless features. When it comes to the safe operation of MMC, the balancing of the Submodules Voltages (SMs) plays a critical role. This paper proposes a balancing approach based on space vector PWM (SVPWM). Unlike the existing techniques, this method generates the switching vectors for the MMC by using only one SVPWM for the upper arm. The lower arm switching vectors are obtained by finding the complement of the upper arm switching vectors. The use of one SVPWM not only simplifies the calculation but also helped in reducing the circulating current in the MMC. The proposed method is varied through simulation using Matlab/Simulink and compared with other available modulation methods. The results validate the ability of the suggested method in balancing the SMs capacitors voltages and reducing the circulating current which will help in reducing the power loss of the PV system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor%20voltage%20balancing" title="capacitor voltage balancing">capacitor voltage balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20current" title=" circulating current"> circulating current</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20multilevel%20converter" title=" modular multilevel converter"> modular multilevel converter</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20system" title=" PV system "> PV system </a> </p> <a href="https://publications.waset.org/abstracts/89168/an-improved-modular-multilevel-converter-voltage-balancing-approach-for-grid-connected-pv-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7968</span> Surveillance of Hepatitis C Virus Genotype Circulating in North India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Prakash">Shantanu Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Suruchi%20Shukla"> Suruchi Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Amita%20Jain"> Amita Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The hepatitis C virus (HCV) is a major public health problem and a leading cause of chronic liver disease. Injection drug use and individuals receiving blood and blood products are the primary modes of HCV transmission. Our study aims to establish the prevalent genotypes/ subtypes of HCV circulating in Uttar Pradesh, North India, as reported from a tertiary care hospital. Methods: It is a retrospective observational analysis of consecutive 404 HCV RNA positive cases referred to our hospital during September 2014 to April 2017. The study was approved by an institutional ethics committee. Written informed consent was taken from each participant. Clinical and demographic details of these patients were recorded using predesigned questionnaires. All the laboratory testing was carried on stored serum sample of enrolled cases. Genotyping of all 404 strains was done by Sanger’s sequencing of the core region. The phylogenetic analysis of 179 HCV strains with high -quality sequencing data was performed. Results: The distribution of prevalent genotypes/ subtypes as noted in the present study was; Genotype (GT)1a [n-101(25%)], GT1b [n-12(2.9%)], GT1c [1(0.25%)], GT3a [275(68.07%)], GT3b [9(2.2%)], GT3g [2(0.49%)], GT3i [3(0.74%)], and GT4a [1(0.24%)]. HCV genotypes GT2, GT5 and GT6 were not detected from our region. Sequence analysis showed high genotypic variability in HCV GT3. Phylogenetic analysis showed that HCV GT3 and GT1 circulating in our region were related to Indian strains reported earlier. Conclusions: HCV genotypes 3a and 1a are commonest circulating genotypes in Uttar Pradesh (UP), India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20C%20virus" title="Hepatitis C virus">Hepatitis C virus</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20variation" title=" genetic variation"> genetic variation</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics" title=" bioinformatics"> bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=HCV" title=" HCV"> HCV</a> </p> <a href="https://publications.waset.org/abstracts/98169/surveillance-of-hepatitis-c-virus-genotype-circulating-in-north-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98169.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7967</span> Eliciting and Confirming Data, Information, Knowledge and Wisdom in a Specialist Health Care Setting - The Wicked Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sinead%20Impey">Sinead Impey</a>, <a href="https://publications.waset.org/abstracts/search?q=Damon%20Berry"> Damon Berry</a>, <a href="https://publications.waset.org/abstracts/search?q=Selma%20Furtado"> Selma Furtado</a>, <a href="https://publications.waset.org/abstracts/search?q=Miriam%20Galvin"> Miriam Galvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Loretto%20Grogan"> Loretto Grogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Orla%20Hardiman"> Orla Hardiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucy%20Hederman"> Lucy Hederman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Heverin"> Mark Heverin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Wade"> Vincent Wade</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Douris"> Linda Douris</a>, <a href="https://publications.waset.org/abstracts/search?q=Declan%20O%27Sullivan"> Declan O'Sullivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaye%20Stephens"> Gaye Stephens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Healthcare is a knowledge-rich environment. This knowledge, while valuable, is not always accessible outside the borders of individual clinics. This research aims to address part of this problem (at a study site) by constructing a maximal data set (knowledge artefact) for motor neurone disease (MND). This data set is proposed as an initial knowledge base for a concurrent project to develop an MND patient data platform. It represents the domain knowledge at the study site for the duration of the research (12 months). A knowledge elicitation method was also developed from the lessons learned during this process - the WICKED method. WICKED is an anagram of the words: eliciting and confirming data, information, knowledge, wisdom. But it is also a reference to the concept of wicked problems, which are complex and challenging, as is eliciting expert knowledge. The method was evaluated at a second site, and benefits and limitations were noted. Benefits include that the method provided a systematic way to manage data, information, knowledge and wisdom (DIKW) from various sources, including healthcare specialists and existing data sets. Limitations surrounded the time required and how the data set produced only represents DIKW known during the research period. Future work is underway to address these limitations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare" title="healthcare">healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20acquisition" title=" knowledge acquisition"> knowledge acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=maximal%20data%20sets" title=" maximal data sets"> maximal data sets</a>, <a href="https://publications.waset.org/abstracts/search?q=action%20design%20science" title=" action design science"> action design science</a> </p> <a href="https://publications.waset.org/abstracts/150267/eliciting-and-confirming-data-information-knowledge-and-wisdom-in-a-specialist-health-care-setting-the-wicked-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7966</span> Sheathless, Viscoelastic Circulating Tumor Cell Separation Using Closed-Loop Microfluidics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyunjung%20Lim">Hyunjung Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeonghun%20Nam"> Jeonghun Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyuk%20Choi"> Hyuk Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-throughput separation is an essential technique for cancer research and diagnosis. Here, we propose a viscoelastic microfluidic device for sheathless, high-throughput isolation of circulating tumor cells (CTCs) from white blood cells. Here, we demonstrate a viscoelastic method for separation and concentration of CTCs using closed-loop microfluidics. Our device is a rectangular straight channel with a low aspect ratio. Also, to achieve high-efficiency, high-throughput processing, we used a polymer solution with low viscosity. At the inlet, CTCs and white blood cells (WBCs) were randomly injected into the microchannel. Due to the viscoelasticity-induced lateral migration to the equilibrium positions, large CTCs could be collected from the side outlet while small WBCs were removed at the center outlet. By recirculating the collected CTCs from the side outlet back to the sample reservoir, continuous separation and concentration of CTCs could be achieved with high separation efficiency (~ 99%). We believe that our device has the potential to be applied in resource-limited clinical settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circulating%20tumor%20cell" title="circulating tumor cell">circulating tumor cell</a>, <a href="https://publications.waset.org/abstracts/search?q=closed-loop%20microfluidics" title=" closed-loop microfluidics"> closed-loop microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic%20fluid" title=" viscoelastic fluid"> viscoelastic fluid</a> </p> <a href="https://publications.waset.org/abstracts/90891/sheathless-viscoelastic-circulating-tumor-cell-separation-using-closed-loop-microfluidics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90891.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7965</span> MicroRNA Profiling Reveals Novel Circulating Biomarkers in Acute Phase of Myocardial Infarction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Maciejak">A.

An early and accurate diagnosis of AMI is essential for optimal treatment. Therefore, new approaches that can complement and improve current strategies for AMI diagnosis are urgently needed. Recent studies have revealed the presence of stable circulating myocardial-derived microRNAs (miRNAs) in human peripheral blood, suggesting that such miRNAs could serve as potential biomarkers of infarction. The present study aimed to identify differentially expressed circulating miRNAs in ST-segment elevation myocardial infarction (STEMI) patients. Materials and methods: miRNA expression profile analysis was performed using Exiqon Serum/Plasma Focus microRNA PCR panel in plasma samples of n=16 patients on the first day of AMI (admission) and in samples from the same patients collected six months after AMI. Selected miRNAs were validated by RT-qPCR using serum samples from an independent set of n=14 AMI patients. Results: The profiling study identified 46 species of plasma miRNAs that were differentially expressed (p < 0.05) on admission compared to six months after AMI. The validation in the independent group of patients confirmed that miR-133b and miR-22-5p were significantly up-regulated upon AMI. Conclusions: Our results suggest that miRNA expression profiling provides better understanding of the changes that occur in the acute phase of MI in the myocardium and could be useful in determination of the potential role of extracellular miRNAs as paracrine signaling molecules. miR-22-5p represents a novel promising biomarker for the diagnosis of acute myocardial infarction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20myocardial%20infarction" title="acute myocardial infarction">acute myocardial infarction</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20microRNAs" title=" circulating microRNAs"> circulating microRNAs</a>, <a href="https://publications.waset.org/abstracts/search?q=microRNA%20expression%20profiling" title=" microRNA expression profiling"> microRNA expression profiling</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-22-5p" title=" miR-22-5p"> miR-22-5p</a> </p> <a href="https://publications.waset.org/abstracts/40104/microrna-profiling-reveals-novel-circulating-biomarkers-in-acute-phase-of-myocardial-infarction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7964</span> Numerical and Experimental Studies on the Characteristic of the Air Distribution in the Wind-Box of a Circulating Fluidized Bed Boiler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaozhou%20Liu">Xiaozhou Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guangyu%20Zhu"> Guangyu Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Zhang"> Yu Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongwei%20Wu"> Hongwei Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wind-box is one of the important components of a Circulating Fluidized Bed (CFB) boiler. The uniformity of air flow in the wind-box of is very important for highly efficient operation of the CFB boiler. Non-uniform air flow distribution within the wind-box can reduce the boiler's thermal efficiency, leading to higher energy consumptions. An effective measure to solve this problem is to install an air flow distributing device in the wind-box. In order to validate the effectiveness of the air flow distributing device, visual and velocity distribution uniformity experiments have been carried out under five different test conditions by using a 1:64 scale model of a 220t/hr CFB boiler. It has been shown that the z component of flow velocity remains almost the same at control cross-sections of the wind-box, with a maximum variation of less than 10%. Moreover, the same methodology has been carried out to a full-scale 220t/hr CFB boiler. The hot test results depict that the thermal efficiency of the boiler has increased from 85.71% to 88.34% when tested with an air flow distributing device in place, which is equivalent to a saving of 5,000 tons of coal per year. The economic benefits of this energy-saving technology have been shown to be very significant, which clearly demonstrates that the technology is worth applying and popularizing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circulating%20fluidized%20bed" title="circulating fluidized bed">circulating fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=CFB" title=" CFB"> CFB</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-box" title=" wind-box"> wind-box</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20flow%20distributing%20device" title=" air flow distributing device"> air flow distributing device</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20experiment" title=" visual experiment"> visual experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20distribution%20uniformity%20experiment" title=" velocity distribution uniformity experiment"> velocity distribution uniformity experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20test" title=" hot test"> hot test</a> </p> <a href="https://publications.waset.org/abstracts/100840/numerical-and-experimental-studies-on-the-characteristic-of-the-air-distribution-in-the-wind-box-of-a-circulating-fluidized-bed-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100840.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7963</span> Genetic Characteristics of Chicken Anemia Virus Circulating in Northern Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hieu%20Van%20Dong">Hieu Van Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Giang%20Thi%20Huong%20Tran"> Giang Thi Huong Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Giap%20Van%20Nguyen"> Giap Van Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tung%20Duy%20Dao"> Tung Duy Dao</a>, <a href="https://publications.waset.org/abstracts/search?q=Vuong%20Nghia%20Bui"> Vuong Nghia Bui</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Thi%20My%20Huynh"> Le Thi My Huynh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yohei%20Takeda"> Yohei Takeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruko%20Ogawa"> Haruko Ogawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunitoshi%20Imai"> Kunitoshi Imai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chicken anemia virus (CAV) has a ubiquitous and worldwide distribution in chicken production. Our group previously reported high seroprevalence of CAV in chickens in northern Vietnam. In the present study, 330 tissue samples collected from commercial and breeder chicken farms in eleven provinces in northern Vietnam were tested for the CAV infection. We found that 157 out of 330 (47.58%) chickens were positive with CAV genes by real-time PCR method. Nine CAV strains obtained from the different location and time were forwarded to the full-length sequence of CAV VP1 gene. Phylogenetic analysis of the Vietnamese CAV vp1 gene indicated that the CAVs circulating in northern Vietnam were divided into three distinct genotypes, II, III, and V, but not clustered with the vaccine strains. Among the three genotypes, genotype III was the major one widely spread in Vietnam, and that included three sub-genotypes, IIIa, IIIb, and IIIc. The Vietnamese CAV strains were closely related to the Chinese, Taiwanese, and USA strains. All the CAV isolates had glutamine at amino acid position 394 in the VP1 gene, suggesting that they might be highly pathogenic strains. One strain was defined to be genotype V, which had not been reported for Vietnamese CAVs. Additional studies are required to further evaluate the pathogenicity of CAV strains circulating in Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken%20anemia%20virus" title="chicken anemia virus">chicken anemia virus</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20characteristics" title=" genetic characteristics"> genetic characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnam" title=" Vietnam"> Vietnam</a> </p> <a href="https://publications.waset.org/abstracts/105191/genetic-characteristics-of-chicken-anemia-virus-circulating-in-northern-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105191.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7962</span> Ontology as Knowledge Capture Tool in Organizations: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Margaretha">Maria Margaretha</a>, <a href="https://publications.waset.org/abstracts/search?q=Dana%20Indra%20Sensuse"> Dana Indra Sensuse</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukman"> Lukman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge capture is a step in knowledge life cycle to get knowledge in the organization. Tacit and explicit knowledge are needed to organize in a path, so the organization will be easy to choose which knowledge will be use. There are many challenges to capture knowledge in the organization, such as researcher must know which knowledge has been validated by an expert, how to get tacit knowledge from experts and make it explicit knowledge, and so on. Besides that, the technology will be a reliable tool to help the researcher to capture knowledge. Some paper wrote how ontology in knowledge management can be used for proposed framework to capture and reuse knowledge.

T cells are known to play an important role in this immune-mediated destruction; however, there is no general consensus regarding alterations in cytokine production or T cell subsets in peripheral blood of patients with type 1 diabetes. Using polychromatic flow cytometry of peripheral blood mononuclear cells (PBMCs), we assessed production of the proinflammatory cytokines IL-21, IFN-γ and IL-17 by memory CD4 T effector (Teff) cells in 69 patients with type 1 diabetes and 61 healthy donors. We found a 21.9% (95% CI 5.8, 40.2; p = 3.9 × 10(-3)) higher frequency of IL-21(+) CD45RA(-) memory CD4(+) Teffs in patients with type 1 diabetes (geometric mean 5.92% [95% CI 5.44, 6.44]) compared with healthy donors (geometric mean 4.88% [95% CI 4.33, 5.50]). In a separate cohort of 30 patients with type 1 diabetes and 32 healthy donors, we assessed the frequency of circulating T follicular helper (Tfh) cells in whole blood. Consistent with the increased production of IL-21, we also found a 14.9% increase in circulating Tfh cells in the patients with type 1 diabetes (95% CI 2.9, 26.9; p = 0.016). Analysis of IL-21 production by PBMCs from a subset of 46 of the 62 donors immunophenotyped for Tfh showed that frequency of Tfh cells was associated with the frequency of IL-21+ cells (r2 = 0.174, p = 0.004). These results indicate that increased IL-21 production is likely to be an aetiological factor in the pathogenesis of type 1 diabetes that could be considered as a potential therapeutic target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=T%20follicular%20helper%20cell" title="T follicular helper cell">T follicular helper cell</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-21" title=" IL-21"> IL-21</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-17" title=" IL-17"> IL-17</a>, <a href="https://publications.waset.org/abstracts/search?q=type%201%20diabetes" title=" type 1 diabetes"> type 1 diabetes</a> </p> <a href="https://publications.waset.org/abstracts/32813/il-21-production-by-cd4-effector-t-cells-and-frequency-of-circulating-follicular-helper-t-cells-are-increased-in-type-1-diabetes-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32813.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7960</span> Microvesicles in Peripheral and Uterine Blood in Women with Atypical Hyperplasia and Endometrioid Endometrial Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Zapala">Barbara Zapala</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Dziechciowski"> Marek Dziechciowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Olaf%20Chmura"> Olaf Chmura</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Piwowar"> Monika Piwowar</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Gawlik"> Katarzyna Gawlik</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorota%20Pawlicka-Gosiewska"> Dorota Pawlicka-Gosiewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Skotniczny"> Krzysztof Skotniczny</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogdan%20Solnica"> Bogdan Solnica</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazimierz%20Pitynski"> Kazimierz Pitynski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BACKGROUND: Endometrial cancer is one of the most common gynecologic malignancy in developed countries.We hypothesized that amount of circulating micro-particles in blood may be connected with the development of endometrial hyperplasia and endometrial cancer. The aim of this study was to measure the micro-particles amount in uterine venous blood and in peripheral venous blood in women with atypical endometrial hyperplasia and endometrioid endometrial cancer. MATERIALS AND METHODS: By using flow cytometry (BD Canto II cytometer) we measured micro-particles amount in citrate plasma samples from peripheral and uterine venous blood of women with atypical hyperplasia of endometrium or endometrial cancer. We determined the amount of total (TF+), endothelial (CD144+) and monocytic (CD14+) micro- particles. RESULTS: Here we show statistically significant higher micro-particle levels in women with atypical hyperplasia of endometrium or endometrial cancer in comparison to healthy women. Performing measurements of the amounts of total, endothelial and monocytic microparticles allow for reliable differentiation between healthy, atypical hyperplasia and endometrial cancer groups. In blood samples from uterine veins the circulating micro-particle levels were significantly different from peripheral blood samples. The micro-particle levels in uterine blood samples were 7-fold higher than in those from peripheral blood of women with both atypical hyperplasia of endometrium and endometrial cancer when compared to the control group of healthy women. CONCLUSION: These results strongly suggested that the level of circulating micro-particles may be a sign of endometrial cancer development, however the detailed study is needed focusing on molecular processes passed through this small circulating molecules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endometrial%20cancer" title="endometrial cancer">endometrial cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=endometrial%20hyperplasia" title=" endometrial hyperplasia"> endometrial hyperplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=microvesicles" title=" microvesicles"> microvesicles</a>, <a href="https://publications.waset.org/abstracts/search?q=uterine%20blood" title=" uterine blood"> uterine blood</a> </p> <a href="https://publications.waset.org/abstracts/123909/microvesicles-in-peripheral-and-uterine-blood-in-women-with-atypical-hyperplasia-and-endometrioid-endometrial-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7959</span> Ontology Mapping with R-GNN for IT Infrastructure: Enhancing Ontology Construction and Knowledge Graph Expansion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Khalov">Andrey Khalov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapid growth of unstructured data necessitates advanced methods for transforming raw information into structured knowledge, particularly in domain-specific contexts such as IT service management and outsourcing. This paper presents a methodology for automatically constructing domain ontologies using the DOLCE framework as the base ontology. The research focuses on expanding ITIL-based ontologies by integrating concepts from ITSMO, followed by the extraction of entities and relationships from domain-specific texts through transformers and statistical methods like formal concept analysis (FCA). In particular, this work introduces an R-GNN-based approach for ontology mapping, enabling more efficient entity extraction and ontology alignment with existing knowledge bases. Additionally, the research explores transfer learning techniques using pre-trained transformer models (e.g., DeBERTa-v3-large) fine-tuned on synthetic datasets generated via large language models such as LLaMA. The resulting ontology, termed IT Ontology (ITO), is evaluated against existing methodologies, highlighting significant improvements in precision and recall. This study advances the field of ontology engineering by automating the extraction, expansion, and refinement of ontologies tailored to the IT domain, thus bridging the gap between unstructured data and actionable knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ontology%20mapping" title="ontology mapping">ontology mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20graphs" title=" knowledge graphs"> knowledge graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=R-GNN" title=" R-GNN"> R-GNN</a>, <a href="https://publications.waset.org/abstracts/search?q=ITIL" title=" ITIL"> ITIL</a>, <a href="https://publications.waset.org/abstracts/search?q=NER" title=" NER"> NER</a> </p> <a href="https://publications.waset.org/abstracts/192575/ontology-mapping-with-r-gnn-for-it-infrastructure-enhancing-ontology-construction-and-knowledge-graph-expansion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192575.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">16</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7958</span> Systematic Process for Constructing an Augmented Reality Display Platform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Chieh%20Hsu">Cheng Chieh Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfred%20Chen"> Alfred Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Pin%20Ma"> Yu-Pin Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Meng-Jie%20Lin"> Meng-Jie Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu%20Pai%20Chiu"> Fu Pai Chiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Yan%20Sie"> Yi-Yan Sie </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, it is attempted to construct an augmented reality display platform (ARDP), and its objectives are two facets, i.e. 1) providing a creative display mode for museums/historical heritages and 2) providing a benchmark for human-computer interaction professionals to build an augmented reality display platform.

The technique is based on Dielectrophoresis and microfluidic device theory. Specifically, the sorting of the cells is realized by adjusting the relation among the sedimentation forces, the drag force provided by the fluid, and the Dielectrophortic force that is relevant to the bias voltage applied on the device. The relation leads to manipulation of the elevation of the cells of the same kind to a height by controlling the bias voltage. Once the cells have been lifted to a position next to the bottom of the cell collection channel, the buffer fluid flashes them into the cell collection channel. Repeated elevation of the cells leads to a complete sorting of the cells in the sample chamber. A proof-of-principle example is presented which verifies the feasibility of the methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20sorter" title="cell sorter">cell sorter</a>, <a href="https://publications.waset.org/abstracts/search?q=CTC%20cell" title=" CTC cell"> CTC cell</a>, <a href="https://publications.waset.org/abstracts/search?q=detection%20and%20discrimination" title=" detection and discrimination"> detection and discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectrophoresisords" title=" dielectrophoresisords"> dielectrophoresisords</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/40753/cell-elevator-a-novel-technique-for-cell-sorting-and-circulating-tumor-cell-detection-and-discrimination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40753.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7955</span> A Novel Nano-Chip Card Assay as Rapid Test for Diagnosis of Lymphatic Filariasis Compared to Nano-Based Enzyme Linked Immunosorbent Assay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aly">Ibrahim Aly</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20Ahmed"> Manal Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20El-Shall"> Mahmoud M. El-Shall</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Filariasis is a parasitic disease caused by small roundworms. The filarial worms are transmitted and spread by blood-feeding black flies and mosquitoes. Lymphatic filariasis (Elephantiasis) is caused by Wuchereriabancrofti, Brugiamalayi, and Brugiatimori. Elimination of Lymphatic filariasis necessitates an increasing demand for valid, reliable, and rapid diagnostic kits. Nanodiagnostics involve the use of nanotechnology in clinical diagnosis to meet the demands for increased sensitivity, specificity, and early detection in less time. The aim of this study was to evaluate the nano-based enzymelinked immunosorbent assay (ELISA) and novel nano-chip card as a rapid test for detection of filarial antigen in serum samples of human filariasis in comparison with traditional -ELISA. Serum samples were collected from an infected human with filarial gathered across Egypt's governorates. After receiving informed consenta total of 45 blood samples of infected individuals residing in different villages in Gharbea governorate, which isa nonendemic region for bancroftianfilariasis, healthy persons living in nonendemic locations (20 persons), as well as sera from 20 other parasites, affected patients were collected. The microfilaria was checked in thick smears of 20 µl night blood samples collected during 20-22 hrs. All of these individuals underwent the following procedures: history taking, clinical examination, and laboratory investigations, which included examination of blood samples for microfilaria using thick blood film and serological tests for detection of the circulating filarial antigen using polyclonal antibody- ELISA, nano-based ELISA, and nano-chip card. In the present study, a recently reported polyoclonal antibody specific to tegumental filarial antigen was used in developing nano-chip card and nano-ELISA compared to traditional ELISA for the detection of circulating filarial antigen in sera of patients with bancroftianfilariasis. The performance of the ELISA was evaluated using 45 serum samples. The ELISA was positive with sera from microfilaremicbancroftianfilariasis patients (n = 36) with a sensitivity of 80 %. Circulating filarial antigen was detected in 39/45 patients who were positive for circulating filarial antigen using nano-ELISA with a sensitivity of 86.6 %. On the other hand, 42 out of 45 patients were positive for circulating filarial antigen using nano-chip card with a sensitivity of 93.3%.In conclusion, using a novel nano-chip assay could potentially be a promising alternative antigen detection test for bancroftianfilariasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lymphatic%20filariasis" title="lymphatic filariasis">lymphatic filariasis</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20diagnosis" title=" rapid diagnosis"> rapid diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=elisa%20technique" title=" elisa technique"> elisa technique</a> </p> <a href="https://publications.waset.org/abstracts/149798/a-novel-nano-chip-card-assay-as-rapid-test-for-diagnosis-of-lymphatic-filariasis-compared-to-nano-based-enzyme-linked-immunosorbent-assay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149798.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7954</span> Changing the Biopower Hierarchy between Women’s Bodily Knowledge and the Medical Knowledge about the Body: The Case of Female Ejaculation and #Notpee</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lior%20B.%20Navon">Lior B. Navon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to investigate how technology, such as social media, can influence the biopower hierarchy between the medical knowledge about the body and women’s bodily knowledge through the case study of the hashtag 'notpee'. In January 2015, the hashtag #notpee, relating to a feminine physiological phenomenon called female ejaculation (FE) or squirting (SQ) started circulating on twitter. This hashtag, born as a reaction to a medical study claiming that SQ is essentially involuntary emission of urine during sexual activity, sparked an unusual public discourse about FE, a phenomenon that is usually not discussed or referred to in socio-legitimate public spheres. This unusual backlash got the attention of women’s magazines and blogs, as well as more mainstream large and respected outlets such as The Guardian and CNN. Both the tweets on twitter, as well as the media coverage of them, were mainly aimed at rejecting the research’s findings. While not offering an alternative and choosing to define the phenomenon by negation, women argued that the fluid extracted was not pee based on their personal experiences. Based on a critical discourse analysis of 742 tweets with the hashtag 'notpee' between January 2015 and January 2016, and of 15 articles covering the backlash, this study suggests that the #notpee backlash challenged the power balance between the medical knowledge about the feminine body and the feminine bodily knowledge through two different, yet related, forms of resistance to biopower. The first resistance is to the authority over knowledge production — who has the power to produce 'true' statements when it comes to the body? Is it the women who experience the phenomenon, or is it the medical institution? The second resistance to biopower has to do with what we regard as facts or veracity. A critical discourse analysis reveals that while both the scientific field, as well as the women arguing against its findings, use empirical information, they, nevertheless, rely on two dichotomic databases- while the scientific research relies on samples from the 'dead like body', these woman are relying on their lived subjective senses as a source for fact making. Nevertheless, while #notpee is asking to change the power relations between the feminine subjective bodily knowledge and the seemingly objective masculine medical knowledge about the body, it by no means dismisses it. These women are essentially asking the medical institution to take into consideration the subjective body as well as the objective one while acknowledging and accepting the power of the latter over knowledge production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopower" title="biopower">biopower</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20ejaculation" title=" female ejaculation"> female ejaculation</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20media" title=" new media"> new media</a>, <a href="https://publications.waset.org/abstracts/search?q=bodily%20knowledge" title=" bodily knowledge "> bodily knowledge </a> </p> <a href="https://publications.waset.org/abstracts/109780/changing-the-biopower-hierarchy-between-womens-bodily-knowledge-and-the-medical-knowledge-about-the-body-the-case-of-female-ejaculation-and-notpee" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109780.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7953</span> On the Construction of Lightweight Circulant Maximum Distance Separable Matrices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qinyi%20Mei">Qinyi Mei</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Ping%20Wang"> Li-Ping Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MDS matrices are of great significance in the design of block ciphers and hash functions.

The importance of knowledge has made organizations to manage their knowledge assets and resources through all multiple knowledge management stages such as: Knowledge Creation, knowledge storage, knowledge sharing and knowledge use. Researches on data mining are continues growing over recent years on both business and educational fields. Data mining is one of the most important steps of the knowledge discovery in databases process aiming to extract implicit, unknown but useful knowledge and it is considered as significant subfield in knowledge management. Data miming have the great potential to help organizations to focus on extracting the most important information on their data warehouses. Data mining tools and techniques can predict future trends and behaviors, allowing businesses to make proactive, knowledge-driven decisions. This review paper explores the applications of data mining techniques in supporting knowledge management process as an effective knowledge discovery technique. In this paper, we identify the relationship between data mining and knowledge management, and then focus on introducing some application of date mining techniques in knowledge management for some real life domains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Data%20Mining" title="Data Mining">Data Mining</a>, <a href="https://publications.waset.org/abstracts/search?q=Knowledge%20management" title=" Knowledge management"> Knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=Knowledge%20discovery" title=" Knowledge discovery"> Knowledge discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=Knowledge%20creation." title=" Knowledge creation."> Knowledge creation.</a> </p> <a href="https://publications.waset.org/abstracts/137030/data-mining-as-a-tool-for-knowledge-management-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137030.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7951</span> Investigating the Impact of Knowledge Management Components on Employee Productivity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javad%20Moghtader%20Kargaran">Javad Moghtader Kargaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, attention to knowledge and management Knowledge as a strategy is very important has taken with economy becoming knowledge-oriented, how and knowing the effective management and integration of different types Knowledge (obvious-implicit) to preserve and create advantage.
